Fig. disaside 23 any liquid that may have passed to the inelevation showing aporti'on ot'agasolene-enterior of the tube 18 through the perforagine'with my improved tank connected theretions 20. with. The operation of the device is as follows:

35 Inthe drawings, 2 represents the outer The liquid, preferably oil or water, is placed shell or receptacle constituting the tank. in in the tank and is drawn outof the lower porwhich the liquid is held and from which it is tion thereof by the pump and after passing circulated around the engine-cylinder. around the cylinder of the engine is carried 3 representsthe cylinder of a gasolene or by the pipe 11 to the receptacle 13. It flows 40 other internal-combustion engine, which may out of the bottom of this receptacle through 0 be. of any suitable construction. A suitable the openingsor perforations 14 into the open pump 4, connected to the tank 2 by a suittrough or receptacle 15. Ittiows out of this able pipe 8 andto the jacket of the cylinder receptacle through the opening 16 and passes by a suitable pipe 9, is arranged to force the ina thin sheet or film over the wire-clothcone 5 liquidfrom thetank through the space within or distributer 17 onto the conical top 23 of the jacket of thecylinder and then through the tank, from which it flows back through the pipes 10 and 11 back to the tank. Any the perforations 24 into the tank, As the p suitable construction of pump may be emliquid is flowing over the distributor 17 the ployed. I have here shown the pump 4, proair which passes upward through the central 5o 'vided With an upright cylinder and having a tube 18 and through the perforations 20 will I00 pass through the liquid and out through the perforation 22. By this means the liquid will be cooled, and when it enters the tank 2 will be of proper temperature to be again circulated around the engine-cylinder. This operation is continued as long as the engine is in operation. The tank 2 may be of any suitable size, and the tube 18, passing through it may be of any suitable diameter. The temperature of the liquid in the tank will be re duced also by passage of the air through the ventilating-tube 18. If preferred, a series of such tubes may be employed instead of the single tube.

I do not limit myself to any particular size, shape, or construction of the tank nor to any particular means for connecting it with the engine. With this tank a small amount of liquid may be employed to cool the cylinder of an internal-combustion engine. I prefer in many instances to use oil as the liquid to be circulated from the tank through the jacket of the engine-cylinder, as there is no danger of freezing when oil is used.

The conical top23 upon the tank and the shield 21 are used principally for the purpose of keeping dust and dirt out of the tank. Where the tank can be sufficiently protected by other means or where such protection is not necessary, one or both of these parts may be omitted, and the liquid may be arranged to flow directly into the open top of the tank. Instead of using the wire-cloth for the cone 17 it is obvious that other material, such as perforated metal or cloth, might be substituted therefor.

While I have shown the tank of circular form and the distributor 17 of conical form, it is obvious that these parts might be of any other form without departing from my invention. It is also obvious that one or more tubes 18, located in any suitable manner, might be used in place of the single tube herein shown.

I claim as my invention 1. The combination, with a tank provided with a tube open at the bottom and projecting through and above the top of said tank, the upper projecting end of said tube being provided with a series of perforations, of a liquid-distributor provided above said tank and inclosing the perforated portion of said tube.

2.. A cooling-tank having a liquid-chamber, and a centrally-arranged tube extending therethrough and open at the bottom to admit air and having its upper end projecting through and above the top of said tank and provided with a series of perforations, and a conical distributor provided above said tank and inclosing the perforated portion of said tube.

3. A cooling apparatus, comprising-a tank having a concave top provided with perforations and a tube extending through said tank and connecting said top with an opening in the tan k-bottom through which air is admitted to said tube, the upper end of said tube projecting above said tank-top and provided with a series of perforations, and a distributor provided above said tank-top and inclosing the perforations therein and the perforated portion of said tube.

4. A cooling apparatus for liquids, comprising a tank having a liquid-chamber, a tube extending therethrough and projecting above the top of the tank and provided with a series of perforations, a distributor inclosing the perforated portion of said tube, a casing inclosing said distributor and tube, and a trough having a series of perforations provided above said casing and tube.

5. The combination, with a tank adapted to contain liquid and having a concave top provided with perforations, of a tube centrally arranged in said tank and communieating at its lower end with an opening in the bottom thereof, the upper end of said tube projecting through said top and provided with a series of perforations, a conical distributor inclosing the perforated portion of said tube and a trough having a series of perforations arranged above said tube.

6. The combination, with a tank adapted to contain a supply of liquid and having a concave top provided with a series of perforations, of a tube projecting above said top and also having a series of perforations, a conical distributor inclosing said tube and the perforations in said top, and a trough havinga series of perforations through which the liquid is discharged upon said distributor.

7. A cooling apparatus, comprising a tank 2 having a concave top provided with a series of perforations, a tube 18 centrally arranged in said tank and having an open lower end communicating with an opening in the bottom of said tank and an upper perforated end projecting above the concave top thereof, a wire-cloth distributor 17 inclosing the perforated upper end of said tube and overhanging the perforations in said top, a shield or casing having a series of perforations in closing said distributor and the upper end of said tube, and a trough having a series of discharge-holes provided above said tube and said shield, substantially as described.

In testimony whereof I have hereunto set my hand, this 9th day of January, 1901, at Minneapolis, Minnesota.
